Comments

Following the surveys we conducted between 2007 and 2008 in the area of Tobatí (Paraguay), we point out that Parodia nigrispina (K. Schumann) F. H. Brandt, is probably close to extinction in the wild. In the formation of the Cerro Tobatí we identified a handful of specimens (7), all young and small (h <17 cm). Another population (about 20 units), difficult to access, is located a few kilometers as the crow flies from the Cerro Tobatí on a similar sandstone formation. The situation deteriorated, compared to data collected by Metzing (1994), who had already assigned the category Endangered, EN to the state of conservation of the taxon: such deterioration was partly caused by the continuing indiscriminate harvesting by local residents for the creation of handicrafts. We therefore see it correct to update the assessment of the conservation status Vulnerable, VU D2 (Hunt et al. 2006, text: 332) to Critically Endangered, CR B1ab(iii,v)+2ab(iii,v);C2a(i).

Our deepening on the distribution areas of P. nigrispina is published in “Observations concerning Parodia (Eriocactus)” on The Cactus Explorer 7: 27-39 (2013).
